I'm playing around with displacement mapping and can quite easily add a texture displacement map to a Carrara primitive and it looks very cool.   However, if I import a model that I created in Wings3d as an OBJ and then texture parts of it with displacement mapping, it doesn't have the same effect, ie none.  Since normal textureing needs to be changed to flat mapping, I wondered if there was something simple I'm missing with a displacement setting?

Anyone tried this?

Here's a Carrara primitive, which is all very well for Borg rip offs, and this is the kind of thing I want to achieve with imported objects.

maybe they've got box/cube mapping in wings? so you wouldn't use flat mapping in wings, if it's box-map in c5.

Have you UV mapped the cube in wings or just made the cube and exported it. Sorry if it sounds obvious but I have on occasion forgot to UVmapp something and just exported it out to find that textures don't work.

I use UVMapper Pro but UVMapper Clasic is FREE and you can do all your different type of UV maps. Box, planer, cylinder, sphere and so on. It also splits vertices if you need to and a big thing is you can save the .obj without normals. This lowers the .obj size by a good third or more.

I've never had any problems using displacement maps on Wings3D created objects with Carrara.
I unwrap or normal map all my UVs with Wings3D UVMapping before exporting. Models made in MAX, I UVW Unwrap them, same effect in Carrara.
Any application with displacement should be able to use a displacement map on any UVMapped object, regardless of what modeller was used.

Miss Nancy:
No cube mapping in Wings. It has Unwrap, Normal Projection, Camera Projection, Cylinder, and Sphere.

Friends don't let friends use booleans.

You can do displacement mapping on anything in  the displacement tag.  You dont have to have flat mapping, You can set up the type of mapping suitable for the object--just as you can in the maintexturing list.
